IMPROVEMENT IN BARREILS.

Specification forming part of Letters Patent No.1 59,064, dated January 26,1875; application iiled November 4, 1874.

To all whom it may concern:

Be it known that l, GEORGE W. BANKER, of the city of New York, State and county1 0f New York, have invented an Improvement in Barrels, of which the following is a specification, reference being had to the accompanying drawing forming part of the same.

My invention relates to that class of barrels and kegs designed to 'contain Volatile liquids, and for that purpose are intended to. be coated on the inside with pitch or some suitable cement. My invention consists in the peculiar construction and combination, hereinafter particularly described, of two barrels, one within the other. f

The accompanying drawing is a central longitudinal section of adonble barrel containing my invention. n

`A is the inner barrel. which may be made either of staves or ot' a single sheet of wood sliced from a round log, and having only a single seam, as described in Letters Patent issued to me Julie 13, 1871, No. 115,807. B is the outer barrel, which may be similarly made. In putting these barrels together one within the other, there may be a free space, i, between them and no contact except at the hoops of the inner barrel, which I recommend to be carefully made and appli-ed of even and uniform thickness throughout, and the diameter of the outer barrel such that its inner surface tits snugly upon the hoops of the inner barrel, so that the outer barrel, while made tight in all its seams, incases tightl the inner one,

permitting no movement of the latter in theV former. The heads of the two barrels are made and combined in the peculiar manner shown in the drawings. The head ot' the inner barrel is preferably, for cheapness, composed of two thicknesses of Wood or plates, c and b, 4as shown in the drawings, which should be'secured together by rivets or cement. The diameter ot' the outer plate Z) coincides With/the external diameter ofthe en d of the barrel A, the said plate resting 011 the ends ofthe staves, the latter being planed oft', as shown, to receive it. The diameter of plate a coincides with theinternal diameter of the barrel A, and sets de vvn Within the end VOt' the sta-ves, its edge being beveled, as

shown, to coincide with the taper of the barrel, forming thus,`in fact, a dovetailed joint, and locking the'head inthe barrel, serving the purpose of a croze. The end hoop c of the barrel A is made to tit over the end of the staves and the edge of the plate b, the outer edge of the hoop coinciding with the outer surface of said plate. Then the head g of the barrel B lits down and rests upon the hoop c and plate A Within the chime of said barrel B, and is beveled on its edge to lit the inclination of the chime. The outer hoop d is then driven on, when it' is evident the several plates composing the combined head will be locked securely in place. For greater strength a stay-hoop, c, may be applied and secured out-side ot' the outer head. In place ot' two plates a b a single one may be employed with an annular beveled notch cut around its edge vto receive the ends ot' the staves of thebarrel A.

' Itis evident that the free space between these two barrels serves to secure the inner barrel against the etl'ect of blows or other violence upon the outer one, there being no contact between them except at the hoops,

where the resistance of thehoops obviatesj damage.

The advantages of the peculiar construction and combination ofthe parts constituting the heads are their simplicity, strength, and convenience of fabrication.

W'hat I claim, and desire to secure byl Letters Patent, is-

The combination of the 'plate a, locked Within the end of the barrel A, the plate b` resting on the said end, and beveled on the edge to tit the hoop c, the plate g resting on the plate b and hoop c, and beveled on its edge to tit the taper of the chime of the barrel B, the hoop (l, and stay-hoop e, all constructed, adapted, and connected as and for the purpose speciled.
